Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127956, here are decompositions:

5 + 127951 = 127956
43 + 127913 = 127956
79 + 127877 = 127956
83 + 127873 = 127956
89 + 127867 = 127956
97 + 127859 = 127956
107 + 127849 = 127956
113 + 127843 = 127956

Showing the first eight; more decompositions exist.
